Review: Flexible and Useful! - Great solution for making almost anything (that can be operated by pushbutton) an IoT device. If you don't want to have to rely on bridges (or "hubs"), this works great. And the value is excellent. OK, so our pictures are pretty redundant to what is shown by the vendor but maybe help perceive scale a bit. We bought a few of these MHCOZY devices to get WiFi control of some access controls from wherever we are in the world. They boot up quickly, connect to WiFi quickly, and if the eWeLink app is to be believed the WiFi radios seem to get good reliable signals in relatively impossible places (steel parking bar motor housing, sliding door motor housing under a layer of sheetmetal and reinforced concrete, etc.). The USB connector is handy for powering up the device for initial configuration before moving it to where it will be used, and the 7-32VAC power inputs mean it can "vamp" power from almost any device it will be crammed into. We have one eWe2.4 running on 12VDC one place and on 24VDC in another. For me it was a snap to set up but on my first try, I was thwarted by needing to put my iPhone on our 2.4GHz WiFi instead of the 5GHz side. One tiny annoyance, the texture on the back of the ABS case means that double-sided tape doesn't stick quite as well as it could (3M VHB for the win). But it seems to stick well enough. This should not really be a review of eWeLink but in our scenario it was mandatory. So far the free version has been fine for us and it seems to play well with Siri. Which means I can do decadent things like saying "hey Siri open my door" when I have my hands full with packages and groceries. Yay. I'm addicted. What else can I automate now, mwahahahahaha...
Review: Manual is Lacking- but for the Money it's great! - I would pay 10x for something that actually worked perfect outside the box, from a US company and a better app/manual. But since it was under $15 I really did not mind getting more involved on the DIY side. I use this to open and close my commercial garage bay in my warehouse. Before, I had to use manual push buttons inside the door to operate. It's a 3 button system, Open (1 press opens door fully), Close (Need to press and HOLD to close), and STOP (emergency stop/used for when you don't want the door fully open). I setup relay one to click on for 1/2 second to activate the UP button. The second relay I set to inch for 18 seconds to close the door. The third relay I set to activate the STOP button- however this does not work as the STOP button seems to be wired in a different manner. I will update when I figure that out. 2 Things that I found difficult: 1- Initial connection was clunky. I do not like to allow location settings, but the app requires a precise location for initial wifi connection. After doing that I setup no problem. 2- The inching did NOT work at first. After several google searches, I found out that the "Mode" button needed to be pressed to activate this. I had to press it 2x to get the inching settings to work in the app. This I found totally pointless- why would you need me to press a physical button when the app allows you to set these times on your phone? It worked after doing this even after unplugging the unit a couple times. I was able to get this to work with Alexa no problem. So now, I can say "Hey Alexa- Open the Garage!" and my garage bay door opens right up. I have a camera facing the door just in case, and will install a wifi outlet to shut the relays off after business hours to reduce security risk. (ie, if a potential intruder shouts "Open the door" the relays would be totally powered off and would not respond). Another major plus- I have forgotten my keys before, and that means a trip home and wasted time. Now if that's the case, I can open the garage! And I can now drive my car right in to the warehouse on hot or rainy days without getting out of the car- provided I don't have too many pallets stacked up inside the door. Overall, it was a great solution to opening and closing a COMMERCIAL garage door. There are many, many ready to go options for RESIDENTIAL garage doors, but the commercial 3-button setups are sadly overlooked by most manufacturers.

### ⭐⭐⭐⭐ Good value, not so good documentation
*by E***R on December 14, 2025*

As others have noted, the instructions are not very helpful. Also, the two buttons on the unit are not labeled. The top one is manual on/off, the middle one is reset/pairing. You need to look at the picture of the circuit board to determine that. Setting up the ewelink account was a bit of a pain. The 60s window for entering the PIN they email you AND picking a password is tight. Initial pairing was wonky. It didn't work at first because it said it created a hot spot network with the name being the device number. I was supposed to connect my phone to the hot spot network, but my phone couldn't see it. I backed out and tried again, and it found the wi-fi network just fine when I paired it. Dunno what happened there. The good news is the device works well once connected. Manual on/off works as expected, and the ewelink app controls it easily. I used the inching feature to simulate the momentary button press on my sauna. In summary, instructions and setup were not so great. Actual functionality is just what I hoped for.
